Batch Test - an overview | ScienceDirect Topics

The number of replicate tests required is dependent on the sample standard deviation that is typical of the ore type in question, and of the format of the flotation test. If the ore is unknown, it is best to perform a set of baseline rougher float tests and empirically obtain an estimate of the sample standard deviation.

How Accurate are THC Potency Tests? - ACS Lab Cannabis

In addition to testing inefficiencies, cannabis itself is not a standard medicine. Cannabis is a plant not a chemical, and therefore every batch, even within the same strain may vary in THC potency as well as other compounds including cannabinoids, terpenes and flavonoids. Inevitably, some degree of deviation is normal and expected.

Standard Deviation Calculator | Find Mean, Variance and SD

Standard deviation is a term which measures the amount of variation or dispersion of a set of values. If the values are close to the mean of the set, it will be a low standard deviation. If the values are spread in a wider range, it will be a high standard deviation.

13.2: SPC- Basic Control Charts- Theory and Construction

A subset average, subset standard deviation, and subset range will be computed for each subset. From these subsets, a grand average, an average standard deviation, and an average range are calculated. The grand average is the average of all subset averages. The average standard deviation is simply the average of subset standard deviations.
